Application Manager and dA Platform use will be limited by the number of CPU cores used by running, production Flink jobs controlled by Application Manager on Kubernetes.
- CPU Core
- A CPU core (or short “core”) is the central billing unit in dA Platform. A CPU core refers to “cpu units”, in Kubernetes. One CPU is for example equivalent to one AWS vCPU, 1 GCP core, 1 Azure vCore (or similar concepts for other cloud providers) or 1 Hyperthread on a bare-metal processor with Hyperthreading (See also the meaning of CPU in the Kubernetes documentation).
Prior to launching a Flink deployment, Application Manager will perform a quota check. This means that a deployment is not rejected for quota overuse when it is created or updated, but only when its desired state is changed to “RUNNING”. Application Manager will never stop a running deployment because of a quota limitation. If a deployment can’t be launched due to the quota, there will be a message in the event log.
